KITZ SCT | FILTERFINE

Model: RD Series
Description
1. A new, high pressure valve that is compactly designed and has a simple external appearance to match today’s needs.
2. Reduced torque and improved durability are added to the manual valve.
3.Simple and compact piping system is made possible by using the automatic valve that has a slim cylinder shape with an air piping in the upper side.
4. Newly added 210K Type, High-Pressure Valve (1/2 inch) satisfies the user seeking Large Volume High-Pressure Valve.
DETAIL
Valve Features: Manual
RD Series consists of High-Pressure Manual Valves featuring a compact body that requires even less torque to operate than the low torque types in the past. Due to the resin-coated handle that is newly employed, you can feel very smooth operation.
A larger window hole and easy-to-see OPEN/CLOSE mark are adopted so that whether it is open or close is instantly noticed. The shunt port of the shunt type can be set to any direction.
Valve Features: Pneumatic
The new cylinder-shaped actuator moves on a minimal line 

pitch, thus it is not necessary to consider the orientation after the installation. Also to be noted is the patented wedge-toggle structure that is incorporated in this valve, and ensures the operation even under high surge pressure.
In addition, rigidity at the conjunction point between the body and actuator is increased so that the reliability is increased. It needs 0.4 ~ 0.7Mpa of operating air pressure, and a stable operation is ensured even at the low limit of the air pressure.

Model: KD Series: High Flow Configurations
DETAIL
Reduced inner capacity
Minimizing the verticle hole to achieve 1.2cm3 of inner capacity (KD 1/4 inch male CVC type under valve open) adds excellent displacement features to this valve.
Minimal seat volume (0.066cm3) 
Reduction of seat surface (0.3cm2) that is in contact with gas enhances the degas features, which in consequence prevents the expansion of plastic caused by the material gases.
Increased seal surface (3.5 times more, compared with previous type of our own) 
Increased seal surface prevent internal leakage caused by mixing-in of foreign particles.
Diaphragm 
Using cobalt alloy of 500 series that is highly resistant to corrosion, and strict control of rolling process ensures a high durability of the product.
Increased operation speed
Using aluminum as a material for piston increases the valve operation speed.
Spring washer structure 

Repulsion of spring water ensures the shut off of the fluid when the valve is closed.
Handle
4 different types, i.e., 90° open/close with lock function, 180° /270° revolving shut off types are available.
